Sending Tu-22M3 in Crimea is Russia’s response to deployment of missile defense in Romania

Russia’s air force is stationing a squadron of long-range, supersonic bombers to Crimea with the option of eventually sending an entire regiment to the peninsula in response to Eastern European NATO allies’ reinforcement plans, according to Russian independent news agency Interfax.
Poland and Romania have agreed to host U.S.-missiles on their territory as part of a missile shield designed to protect NATO allies from potential attacks. Last month a representative of Russia’s Security Council, the state defence advisory body, issued an implicit threat to the two countries saying they had turned themselves into “targets” for Russia’s military.
Russia has previously threatened to redeploy more servicemen, tanks and artillery to its western borders, if the U.S. decides to store more military vehicles in Poland and the Baltic countries.
